Nostoc punctiforme is a species of filamentous cyanobacterium. Under non-limiting nutritional environmental conditions, its filaments are composed of photosynthetic vegetative cells; upon nutrient limitation, some of these cells undergo differentiation into heterocysts, akinetes or hormogonia. [1]

Contents

N. punctiforme is one of the Nostoc strains able to maintain diazotrophic symbiosis with higher plants such as the bryophytes Anthocerus punctatus and Blasia pusilla , water ferns from the genus Azolla , the cycads Macrozamia spp., and the angiosperm Gunnera . [2]

Applications

Modified Nostoc punctiforme intein (Npu DnaE split intein) is used for a self-cleaving protein purification (e.g. iCapTag™). [3] [4]
